Removing Tail Lamp Lenses

[DB S600]

Does anyone know where I can find instructions to remove the 2 "inner" tail lamp lenses (that are located on the lift down portion of the tailgate) as well as the third brake light lense on an '04 LX470? I have figured out how to remove the 2 "outter" lamps, but I am not able to figure out the others. I'm trying to add a tint to the lenses - I've seen it done on another LX and a very light tinting has a dramatic effect on the car's rear end. Later, JJ.
